Their Enable checkbox is ticked, and greyed-out. Other alarms have a pulldown in their control panel that allows the user to set the level.
- Page 20 GUIDE TO INSTALLATION AND OPERATION Video – Format Mismatch The user sets an expected format for each input using the pulldown in the control panel. The HCO-3901 compares this with the actual format detected at the input, and flags an error if they do not match, after a 0.5 second delay.
- Page 21 GUIDE TO INSTALLATION AND OPERATION Video – Black Detect This error detects the presence of a continuous black signal for a period of time; the error is flagged only when the time duration criterion has been satisfied. This error can be Enabled using the checkbox, and the level set to 1, 2 or OFF.
- Page 22 GUIDE TO INSTALLATION AND OPERATION • Set Duration (sec) – sets the time interval over which a freeze must be continuously detected before the error is flagged. The nominal range of durations is 1 to 90 seconds. There is an additional 0.5 seconds intrinsic to the error detection algorithm that will prevent switching when there are nearly-coincident errors at the two inputs.

GUIDE TO INSTALLATION AND OPERATION Note that when the ALC option is active but clean switch is not active (either the option has not been purchased, or is available but not activated), the reference source is forced to the selected input. The user can select a different reference here, but that selection will only become active when clean switch is activated. - Page 27 GUIDE TO INSTALLATION AND OPERATION Note: The ALC works with PCM audio. If non-PCM audio like Dolby-E or AC-3 is fed to the module, it will be ignored and all the program channels will be bypassed to prevent interference with the other PCM audio channel 3.4.8.1 Config tab Channels per program Pull-downs are available to select the number of channels...
- Page 28 GUIDE TO INSTALLATION AND OPERATION ability to tightly follow the target output loudness. Using this preset, the program content will sound a little more dense, while keeping most of the original program dynamic range. • Factory Standard – The ALC applies moderate dynamic range compression on the audio program content. The overall response time is also moderate, which allows the ALC to follow the target output loudness quite well.

Page 29: The Fingerprint Panel
GUIDE TO INSTALLATION AND OPERATION The ALC Fast Mode Response kicks in whenever the input loudness goes over the Fast Mode Threshold and loudness is reduced, in a few milliseconds. The Fast Mode Threshold is given in dB with respect to the target loudness and ranges from 2 to 12 dB, in dB steps. - Page 30 GUIDE TO INSTALLATION AND OPERATION Note: The windows for Inputs 1 and 2 can be adjusted independently. The PGM Output window settings follow those of the selected input, and are shown in the tab but cannot be adjusted there.
